The Serra da Mantiqueira Environmental Protection Area is a Sustainable Use Conservation Unit of the Mata Atlântica Biosphere Reserve in the states of São Paulo, Rio de Janeiro and Minas Gerais. Among others, it includes the colonial nucleus of Visconde de Mauá and surrounds the Itatiaia National Park and Campos do Jordão State Park (see map). The Mantiqueira mountain chain is of Cenozoic origin (see geology) and parallels the coastal Serra do Mar for about 320 km. It is limited to the northwest by the Paraná Basin and to the southeast by the Upper Paraíba Valley.
